Skilled manipulators can be quite seductive and charming. Still, I confess readily in my book In Sheep’s Clothing that when I first began my clinical research, I wondered how the victims of covert-aggressors could be so blind to their manipulator’s true character without having a lot of issues of their own. Only after I got much deeper into the study of covert aggressors did it become clear to me not only how adept they can often be at using various tactics but also how powerful the tactics themselves inherently are.
